Abstract
Description
Die Erfindung betrifft eine Pegeleinstellvorrichtung.The The invention relates to a level adjusting device.
Eine
Pegeleinstellvorrichtung dieser Art ist in
Die
Soll-Amplitude des Referenzdetektors
Bei den Pegeleinstellvorrichtungen dieser Art wird das Referenzsignal stets analog erzeugt, eine Amplitudenmodulation ist hierbei nur durch eine analoge Multiplikation, z.B. mit einem Mischer, möglich.at the level adjusting devices of this type become the reference signal always generated analog, an amplitude modulation is only by an analog multiplication, e.g. with a mixer, possible.
Es ist die Aufgabe der Erfindung, eine Pegeleinstellvorrichtung dieser Art so zu verbessern, dass die Einstellung der Amplitude des Hochfrequenzsignals und auch eine eventuelle Modulation einfacher und genauer möglich wird.It The object of the invention is a Pegeleinstellvorrichtung this Type to improve so that the adjustment of the amplitude of the high-frequency signal and also a possible modulation is easier and more accurate possible.
Diese Aufgabe wird durch die kennzeichnende Merkmale des Anspruchs 1 gelöst. Vorteilhafte Weiterbildungen ergeben sich aus den Unteransprüchen.These The object is solved by the characterizing features of claim 1. Advantageous developments emerge from the dependent claims.
Durch die erfindungsgemäße Erzeugung des Referenzsignals auf digitalem Wege kann die Amplitude des Referenzsignals und damit auch die Amplitude des Ausgangssignals des Signalgenerators wesentlich einfacher und genauer als mit den bisher üblichen analogen Anordnungen durchgeführt werden. Außerdem ist eine sehr einfache und genaue Variation des Modulationsgrades einer eventuellen Amplitudenmodulation möglich. In beiden Fällen müssen nämlich nur Faktoren auf der digitalen Seite verändert werden. Ein weiterer Vorteil der erfindungsgemäßen Pegeleinstellvorrichtung ist, dass damit auch auf einfache Weise ein im Signalgenerator erzeugtes I/Q-Signal pegelgeregelt werden kann.By the production according to the invention the reference signal in a digital way, the amplitude of the reference signal and thus also the amplitude of the output signal of the signal generator much easier and more accurate than usual analog arrangements performed become. Furthermore is a very simple and accurate variation of the degree of modulation possible amplitude modulation possible. In both cases, only Factors on the digital side are changed. Another Advantage of the level adjusting device according to the invention is that so easily a generated in the signal generator I / Q signal can be level controlled.
Die Erfindung wird im folgenden anhand schematischer Zeichnungen an Ausführungsbeispielen näher erläutert. Es zeigen:The The invention will be described below with reference to schematic drawings embodiments explained in more detail. It demonstrate:
